Description
Technical Field
[0001] The utility model belongs to the technical field of nail shooting, and specifically relates to a nail for pressure drainage shooting. Background Art
[0002] A nail is a professional tool for fixing objects and is widely used in fields such as construction, decoration, and furniture manufacturing. Traditional nails usually consist of metal nails, gunpowder, and a primer device. The kinetic energy generated by the explosion of gunpowder is used to drive the metal nail into the base material. A nail gun is a special tool for firing nails. It ignites gunpowder through a trigger device to generate a powerful thrust and shoots the nail into the target object at a high speed. The advantages of nails are fast construction speed, simple operation, and good fixing effect. However, in some special application scenarios, traditional nails cannot meet the requirements, especially in the case of pressure monitoring or carrier sampling in a pressurized pipeline, the limitations of traditional nails become particularly prominent.
[0003] During the maintenance and monitoring of traditional pressurized pipelines, it is necessary to monitor the pressure inside the pipeline in real time, and sometimes it is also necessary to collect samples of the medium inside the pipeline. This process usually needs to be carried out without stopping the pipeline operation, which involves the problem of pressure drainage. Traditional methods usually involve cutting the pipeline or using special pressure tapping tools, but there are the following obvious drawbacks: Traditional methods often require professionals to perform complex operations, which not only take a long time but also are prone to human errors. Pressure tapping tools are expensive, and each operation requires a large amount of time and manpower, resulting in a high overall maintenance cost. Cutting or tapping operations may cause damage to the pipeline, leading to leakage accidents and even environmental pollution. Traditional tapping methods may damage the pipeline wall, reducing the overall life and safety of the pipeline. Traditional methods cannot achieve fast and effective pressure drainage, especially in emergency situations, and cannot respond quickly. Summary of the Utility Model
[0004] In view of this, a nail for pressure drainage shooting provided by the utility model solves the drawback of high construction complexity of traditional nails, shortens the time required for pressure drainage, and improves work efficiency.
[0005] The utility model is implemented as follows:
[0006] The utility model provides a nail for pressure drainage shooting, which sequentially includes a primer cap, a cartridge case, and a stainless steel nail from top to bottom. The cartridge case is a hollow cylindrical shape with a hollow interior. The stainless steel nail is provided with an outer opening and an inner opening, and the outer opening is connected to the inner opening through an inclined hole.
[0007] The technical effects of a nail for pressure - drainage shooting provided by the present utility model are as follows: This design enables the nail, after being shot into a pressurized pipeline, to lead out the carriers (such as water, gas, oil, etc.) inside the pipeline through the inclined through - holes, achieving pressure - drainage while maintaining the sealing of the pipeline. The stainless - steel material has excellent corrosion resistance and strength, enabling the nail to maintain good performance under various environmental conditions and extending the service life of the nail.
[0008] On the basis of the above - mentioned technical solution, a nail for pressure - drainage shooting of the present utility model can be further improved as follows:

[0015] Further, the diameters of the outer opening, the inner opening, and the inclined hole are all smaller than the diameter of the stainless - steel nail.
[0016] Further, the diameters of the outer opening and the inner opening are between 1 mm and 1.5 mm, and the diameters of the outer opening, the inner opening, and the inclined hole are equal.
[0017] The beneficial effect of adopting the above - mentioned improvement scheme is that the moderate diameter design enables the nail to effectively perform pressure - drainage shooting without affecting the normal operation of the pipeline due to too large a hole diameter.
[0018] Further, the primer cap and the cartridge case are fixedly connected by threads or buckles.
[0019] Furthermore, several card slots are provided on the outer surface of the percussion cap, and corresponding protrusions are provided on the inner surface of the cartridge case.

[0051] Further, in the above technical solution, a plurality of card slots 11 are provided on the outer surface of the primer 10, and corresponding protrusions 22 are provided on the inner surface of the cartridge case 20. The card slots 11 and the protrusions 22 are matched, and the widths of the card slots 11 and the protrusions 22 are less than 1 / 2 of the distance between the primers 10.
[0052] Further, in the above technical solution, the cartridge case 20 and the stainless steel nail 30 are connected by machining or welding.

[0061] Snap-fastening:
[0062] The snap-fastening can be designed in the form of multi-point engagement. That is, multiple snaps or slots are provided at the edge of the primer cap, and correspondingly, multiple snap holes or slots are provided at the opening of the cartridge case, so that there are stable fixing points in the entire connection area.
[0063] Snap - type fixation enables assembly to be completed through a simple pressing action. Meanwhile, a spring or other elastic element is provided inside the nail, ensuring that the snap can tightly fasten after assembly to prevent loosening.
[0064] This connection method is not only convenient for quick assembly and disassembly but also can maintain good stability during use.

[0068] Specifically, the principle of the present utility model is:
[0069] Oblique through - hole design:
[0070] Function mechanism: An oblique through - hole with a diameter of about 1 mm is formed on the oblique side of the nail by electrical pulse machining. When the nail is shot into the pressurized pipeline, the lower end of the oblique through - hole penetrates into the pipeline interior, while the upper end is exposed outside. Since the pressure inside the pipeline is higher than the external atmospheric pressure, the carrier (such as water, gas, oil, etc.) inside the pipeline will be pressed through the oblique through - hole into the outside of the nail to achieve pressurized drainage.
[0071] Technical advantages: The design of the oblique through - hole enables the nail to start working immediately after being shot into the pipeline without the need for additional connection or fixing devices. The size of the oblique through - hole is appropriate, which can ensure sufficient flow rate and will not affect the normal operation of the pipeline due to too large an aperture.
[0072] Structural optimization:
[0073] Material selection: The main part of the nail is made of stainless - steel material, which has excellent corrosion resistance and strength. The selection of stainless - steel material enables the nail to maintain good performance under various environmental conditions and extends the service life of the nail.
[0074] Connection between the primer cap and the cartridge case: A locking mechanism is provided between the primer cap and the cartridge case to prevent accidental detachment during transportation or storage. Specifically, small protrusions or grooves that engage with each other can be designed on the contact surface between the primer cap and the cartridge case. When the two are assembled in place, these protrusions or grooves will fit into each other to form a physical lock. In addition, snap-fastening can be used. The assembly is completed by a simple pressing action, and a spring or other elastic element is provided inside the nail to ensure that the snap fastener can tightly hold after assembly to prevent loosening;
[0075] Sealing design: The upper end of the nail is sealed and connected to the pipeline through a seal. The seal is made of high-pressure resistant material to ensure that a good sealing effect can be formed after the nail is shot into the pipeline to prevent leakage;
[0076] Working principle:
[0077] Firing process: When the nail is fired using a nail gun, the gunpowder inside the nail gun is ignited, generating a powerful thrust to shoot the nail into the pressurized pipeline at high speed. The locking mechanism between the primer cap and the cartridge case of the nail ensures stability during the firing process;
[0078] Pressurized drainage: When the nail is shot into the pipeline, the lower end of the inclined through-hole extends deep into the pipeline. Under the action of the pipeline pressure, the carrier inside the pipeline is pressed into the outside of the nail through the inclined through-hole. The upper end of the nail forms a sealed connection with the pipeline through the seal, ensuring the effect of pressurized drainage.
